Never mind that fact that it's a friendly, and never mind the fact that neither team are fully up to speed yet, when Manchester United face Barcelona then it is always worth watching.

The pair will go head-to-head in Wednesday night's pre-season clash at the very American-sounding FedExField (no spaces), in a clash which is sure to be enjoyed by the locals present and over-analysed by those of watching on from afar.

But if you're not planning to stay up all night, just what can you expect to go down?

Well these seven things for starters.

Neymar will do something brilliant that makes everyone joke that he really is worth £197m

Did you see that goal against Juventus?! We've got another one of those in mind here.

Again, this is *only* a friendly, but you've got bear in mind that we are at the height of transfer speculation season, and so anything brilliant that the Brazilian magician does will be seized upon.

And he does a lot of brilliant things.

Paul Pogba will make one small error - and everyone will say that he's not worth half a Neymar

Because while one player can live by the transfer sword, it is the law that another has to die by it.

Barely a day has gone by since Pogba's £89m move to United last summer that the deal was discussed by someone, and even though the crazy fees flying around these days seem to make that figure seem a little more sane by comparison, he still can't escape it.

Not with Neymar on the pitch, anyway.

The players will walk out carrying Burger King paper bags and wearing cardboard crowns

Well Ronald McDonald got his day in the sun during United's clash with Real Madrid, so this would only be fair, right?

Jose Mourinho will make a point of showing respect to Barcelona

A friendly? No pressure? Nothing on the result?

What better moment for Jose Mourinho to pretend that he's actually fine with a club that has come to haunt him in various ways ever since he left his assistant role there in 2000?

He's totally fine with them, honest. Fine. He's fine...

Ander Herrera will be spotted talking to a Barcelona player… and a tapping up storm ensues

The Spanish midfielder might not play because of a back injury he sustained in United's previous friendly against Real Madrid, but even if he doesn't then he's likely to be snapped on the sidelines in the American capital.

The commentator will make an inevitable NFL gag when Romelu Lukaku fires a shot over the bar

Because let's be honest, that's exactly what we'd do.

And finally, no-one will know what the hell the result means for the International Champions Cup format

So Dortmund beat Milan in China, while in Singapore Bayern Munich beat Chelsea, meaning that because Tottenham beat PSG in Orlando then all United have to do is match Real Madrid's result when they play Man City - who United beat - in Los Angeles on Thursday.
